Our valve bodies are dynomometer-tested on our Answermatic 4000 Valve Body Test System using Superflow WinDyn software and are built in-house, specifically calibrated to work with Goerend torque converters along with other products of ours. We offer constant pressure and manual valve body setups. Please take the Valve Body Questionnaire to set up a custom valve body to fit your truck's specifications.
Some valve bodies are limited on how much line pressure that can be run due to the stretching and deformation of the torque converter's impeller due to over-pressurization, known as ballooning. Our apply-regulated valve body regulates torque converter lock-up apply pressure separately from main line pressure. This allows higher pressures in the transmission for holding smaller diameter transmission clutches, while a lower, safe pressure is used to hold the large diameter converter clutches without damaging the torque converter, pump, or shaft.
This apply regulation can be added to any Goerend valve body and can be set up for racing applications or for daily driver towing. Testing has shown a significant decrease in the harshness of the 3-4 shift that 3rd generation trucks are known for when adding a triple disc torque converter. Additional parts required: 48RE pump stator support seal, Goerend triple disc torque converter.
We utilize a technique that has been in the gas racing world for years, the torque converter dump valve, which drains oil from the torque converter while spooling at the line, allowing the engine to gain RPM and rise to the desired level before launching. When coupled with a Goerend non-lock torque converter and constant pressure manual trans-brake valve body, drivers have seen faster and more consistent runs. The dump valve setup requires no major changes to the transmission, only additional wiring to control the solenoids. Other advantages to this system are less rotational weight and overall maintenance, with higher pressure to hold the transmission clutches and no torque converter clutches.
